TIDA-00845 is a dual-port USB 2.0 hub with the ability to withstand a short of up to 18-V DC on both downstream ports, as well as Level 4 IEC 61000-4-2 ESD protection, overcurrent conditions, and shorts to ground. This protection is provided by an integrated protection device -the TPD3S714-Q1. With short-to-battery (STB) protection, short-circuit protection, and a fixed current-limit load switch on both downstream ports, the TUSB4020BI USB 2.0 hub is isolated and protected from overvoltage and overcurrent conditions. Downstream port 1 includes a STB test simulator for applying 18-V DC, and two TPD3S714-Q1s to protect both the hub and a peripheral for easily demonstrating USB STB protection functionality.
Возможности:

Fully functional USB hub with built-in short-to-battery test simulator on downstream port 1 Short-to-battery protection (up to 18 V) on VBUS, DP/DM Overcurrent protection current limit: 550 mA IEC 61000-4-2 (Level 4) system-level ESD protection at VBUS, DP/DM Short-to-ground protection on VBUS

TIDA-00987 is a reference design for Automotive Media Ports that require data transfer. This design has the capability to support USB 2.0 and USB 3.0 data through a 15W USB Type-C™ port. Customers can accelerate their media port systems by taking advantage of a complete reference design comprised of analog AEC-Q100 qualified integrated circuits (ICs) that are CISPR 25 Class 5 tested. This design creates a robust, flexible solution which allows the system to charge both USB Type-C and legacy devices all within a small 1in x 2.5in solution.
Возможности:

The LM74610-Q1 smart diode emulates an ideal diode rectifier and protects downstream devices in the case of reverse polarity. The TPS25810-Q1 and TPS254900-Q1 provide negotiation over the CC1/CC2 and D+/D- lines respectively to enable charging of either USB Type-C or legacy downstream devices. Small solution size based on typical media interface board dimensions of 2.5in x 1in. The components in this system provide Short-to-Battery protection and load dump protection against input transients up to 40V. By combining the HD3SS3212 with the TPD4E05U06-Q1 and optimized layout, this design demonstrates SuperSpeed compatibility with the USB Type-C connector without signal degradation. The automotive grade LM53635-Q1 optimizes the power supply through its unique Hotrod package and reduces parasitics in order to mitigate EMI without interfering with AM or FM band frequencies.
